I. Before you watch the video answer the following questions.
The title of the video is "Algebra I"
What do you think this video will be about? I think that the video will treat about the branch of mathematics “algebra” as its title mentions and it will speak about uses numbers, letters and signs to generalize the various arithmetic operations.
Mention five words you think you might listen to in the video. Numbers
Signs
Equations
Operations
Arithmetic
Mr. Mc Call is solving three types of equations in this video. Which are those types of equations?
Equation with a variable on one side with a fraction.
Equation with one variable in one side using the distributive property.
Equation with multiple variables solving for one variable.
2. What are the two keys he mentions for solving any equation? In numbers that are in addition or subtraction in the equation, place the proper number for zero. The numbers that are multiplying or dividing the variable, multiply by its inverse.
3. a. Mention the steps he takes to solve the 1st problem. Find the unknown or variable “x”. Place the number which it is subtracting to the other side of the equation, so as to leave the variable "x" alone on one side of the equation. Multiply both sides by the inverse of the number that multiplies the variable "x", so let the variable "x" clear. b. What kind of equation is this one?
It is an equation with one variable "x" with a fraction on one side of the equation.
4. a. Mention the steps he takes to solve the 2nd problem. Use the distributive property. Sum the terms containing the variable "x". Place the number which it is subtracting or summing to the other side of the equation, so as to leave the variable "x" alone on one side of the equation. Multiply both sides by the inverse of the number that multiplies the variable "x", so let the variable "x" clear.
b. What kind of equation is this one? It is an equation with a variable "x", using the distributive property.
5. a. Mention the steps he takes to solve the 3rd problem. Find the variable you are asking us to solve the equation. Skip the variables that do not contain the requested variable "w" on the other side of the equation equal. Multiply both sides by the inverse of the number that multiplies the variable "w", so let the variable "w" clear.
b. What kind of equation is this one? It is an equation with multiple variables, three specifically.
6. a. Mention the steps he takes to solve the 4th problem. Find the variable you are asking us to solve the equation. Multiply both sides by the inverse of the number that divides the variable "b". Skip the variables that do not contain the requested variable "b" on the other side of the equation equal, so let variable “b” clear. b. What kind of equation is this one? It is an equation with multiple variables, three specifically. c. What’s the difference between problem 3 and problem 4?
The difference between problem 3 and 4 is that in problem 3 first skip the variables that do not contain the requested variable on the other side of the equation equal and later multiply both sides by the inverse of the number that multiplies the variable, so let the variable clear, and while in problem 4 is the opposite; first multiply both sides by the inverse of the number that multiplies the variable and later skip the variables that do not contain the requested variable on the other side of the equation equal, so let the variable clear. 7. Did you like the video?
Yes, I remembered when I was in the high school and the teacher was teaching me about this subject and my teacher was very good explaining it.
8. What new things did you learn? I think I know the subject exposed, it is for this reason that I feel I don’tdidn't learned something new.
Nice job
